Ingredients

Scale
  • 2 ½ cups (315 g) all-purpose flour, sifted
  • 2 ½ teaspoons (12 g) baking powder
  • ½ teaspoon (3 g) salt
  • 1 cup (227 g) unsalted butter, softened
  • 2 cups (400 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tablespoon (15 ml) pure vanilla extract
  • 1 cup (240 ml) whole milk, room temperature
  • 1 cup (227 g) unsalted butter, softened (for buttercream)
  • 4 cups (480 g) powdered sugar, sifted
  • 2 teaspoons (10 ml) pure vanilla extract (for buttercream)
  • 2–4 tablespoons (30–60 ml) heavy cream or whole milk (for buttercream)
  • Gel food coloring in your school colors
  • Pinch of salt (for buttercream)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch pan with butter or non-stick spray, then dust with flour.
  2. In a medium bowl, sift together the flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat the softened butter and granulated sugar with a mixer on medium speed until light and fluffy, about 3-5 minutes.
  4. Add eggs one at a time, beating well after each addition. Mix in the vanilla extract.
  5. Reduce mixer speed to low. Add the dry ingredients in three parts, alternating with the milk, starting and ending with dry ingredients. Mix just until combined after each addition.
  6. Pour the batter into the prepared pan and smooth the top with a spatula.
  7. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean and the cake feels springy.
  8. Cool the cake completely in the pan on a wire rack, about 1 hour.
  9. To make the buttercream, beat softened butter on medium speed until creamy, about 1-2 minutes.
  10. Gradually add powdered sugar on low speed to avoid a sugar cloud.
  11. Add vanilla extract, heavy cream or milk, and a pinch of salt. Beat until smooth and spreadable.
  12. Divide buttercream into bowls and tint with gel food coloring to desired shades.
  13. Spread or pipe the buttercream evenly over the cooled cake, using piping bags or spatulas to create custom school colors designs.

Notes

Use room temperature ingredients for best results. Do not overmix the batter to keep the cake tender. Cool cake completely before frosting to prevent melting. Use gel food coloring for vibrant frosting colors. Adjust buttercream consistency with milk or powdered sugar as needed.
